SUBFRAME FOR WINDOWS, DOORS, AND THE LIKE.

Application led July 18,

In the construction of houses and buildings much trouble and expensehave been occasioned in making a satisfactory lit of the window or doorframe in the window opening. This has been especially true Where metalCasement windows or doors are to be put in, it not being practicable toalter such frames to accommodate the openings but necessary tostraighten out the irregularities made by brick layers, stonemasons andcarl apparent to those skilled in the art.

The invention is embodied inthe example herein shown and described, thefeatures of novelty being pointed out in the claims.

In the accompanying drawings- Figure 1 is a front elevation of thesubframe according to our invention.

Fig. 2 is a vertical section on the line II, Fig. 1,-sh0wing thesubframe set in a wall and the window installed therein.

Fig. 3 is a horizontal section on the 'line III, Fig. 1.

Figs. 4., 5 and 6 show fractions of the to a side and bottom,respectively, of the sugframe before they are bolted together.

Fig. 7 is a cross section of a modification.

The to bar of the subframe is, as shown, compose of two bent stri s 10and 11 of metal preferably spot-wel ed together longitudinally to form afin or web that occupies the space between thel two angle bars 12 and 13placed across the top of the window opening. The piece 10 has anoutwardly standing lip 10a that is slightly bent downward to shed water,and the piece 11 has an inwardly standing horizontal lip 11" to whichthe t-o bar 14 of the window frame is bolted. The p ane of the lip 11ais belowthat of the lip 1.0a so that the an lar bar of the window framecan be fit and olted to it.

The side'bars of the subframe are each similarly formed, that is, eachis composed of two strips 16 and 17 of metal angularly vbent and spotwelded togetherto form a fin 1927. Vserial No. 206,496.

or web that is located in the mortar space of the bricks or stones, thestrip 16 having an outwardly bent portion 16JL that serves as a stop orguide for the workmen in building the wall to form the Window openingwhile the strip 17 has a bent portion 17 a to which the window frame isbolted in the same manner that the top of the window frame is bolted tothe portion 11a. The plane of the lip 17,a is disalined inwardly asrespects the plane of the stop 16a, the latter being outermost.

The bottom bar of the subframe can consist of a single ply strip ofmetal 18, it being located between the inner and outer sills and havingits upper edge bent outwardly and downwardly at 18 stone sill and tohave bolted to it the lower bar of the window frame. The four pieces ofthe subframe formed as described and as shown in Figs. 4, 5 and 6 arebolted together by bolts passes through holes in the ends thereof suchas shown at 20 to form the complete subframe as shown in Fig. 1.

In the example shown the window frame is shown as having hinged theretoat 21. a glazed frame 22. 5

Instead of welding two strips together to form bars of the subframe flatstrips can be Y longitudinally folded and bent to form the lateralextensions as shown in section in Fig. 7.

fter the window frame has been put in' place the plaster is applied asshown at 23 and 24, the usual trim 25 and wooden inner sill 26 put inplace.

In the invention is, of course, ful as a subframe for a door.

The forms of the parts can be changed without departing from the gist ofthe invention as claimed.

What we claim is.: i,

1. A metallic subframe for a window or door, a bar of which subframeincludes an outwardl projecting lin or web portion to engage t el walloi. the building in which the window or door is to be installed andportions projecting laterally as respects said n or web portions andoppositely as respects each other.

2. A .metallic subframe for a window or door, a bar of which subframeincludes an outwardly projecting tin or web portion to engage the wallof the building in which the window or door is to' be installed andporequally useto stand above the.

tions projecting laterally as respects said tins or Web portions andolppositely in oli'set planes as respects each other. y

3. A metallic subframe for a Window or 5 door, a bar of which subframeincludes an outwardly projecting fin or Web portion to engage the Wallof the building in which the Window or door is to be installed andportions projecting laterally as respects said 10 fin or Web portion,one of said laterally projecting portions constituting a Wall buildingstop and the other a member to which the Window or door frame is to besecured.

4. A Window or door sub-frame having an outwardly projecting iin or Webportion to engage the Wall of the building in which the Window or dooris to be installed and portions projecting laterally as respects saidfin 0r web portion one of said laterally projecting portions to form aWall building stop and the other of said projecting portions havingsecured to it the Window or door frame.
